Don't know about compatibility of these disks, but check out the link and decide for yourself. My 104 is in the post (can't wait!!), but I still bought a ten pack of the Infiniti DVD-Rs, and I can tell you that, at least by appearance, they are TOP quality. I will repost when I have written some of them, to let you know how I get on with them in the Pioneer. h**p://www.lordofthedeals.co.uk/acatalog/DVD_media.html Arky ;o)
